Re: AsyncProxy and ActivityMapper

I simply do (note that I have a custom AbstractActivity class that contains a setPlace method to tell the activity which place to use):

public class MainActivityMapper implements ActivityMapper {

  private Provider<AsyncActivityProxy<MyActivity1> activity1;

  @Inject

  public MainActivityMapper(Provider<AsyncActivityProxy<MyActivity1>> activity1Provider) {

    activity1 = activity1Provider;

  }

  public Activity getActivity(Place place) {

    if(place instanceof Place1) {

      AsyncActivityProxy<MyActivity1> activity = activity1.get();

      activity.setPlace(place);

      return activity;

    }

    return null;

  }

}

And in my GinModule I do:

bind(AcitivityMapper.class).annotatedWith(Names.named(DisplayArea.MAIN)).to(MainAcitivtyMapper.class)

where DisplayArea.MAIN is simply a String constant "main".

Now I can inject the MainActivityMapper using

public MyExampleConstructor(@Named(DisplayArea.MAIN) ActivityMapper mainActivitymapper) { ..... }

But as you generally only need the ActivityManager I added the following code to the GinModule to be able to inject a MainActivityManager which contains the MainActivityMapper:

@Provides

@Singleton

@Named(DisplayArea.MAIN)

public ActivityManager getMainActivityManager(EventBus eventBus, @Named(DisplayArea.MAIN) ActivityMapper mapper) {

  return new ActivityManager(mapper, eventBus);

}

Maybe there are better ways but this works for me so far and everything I need is injected. I hope it helps.
